Weex Vue Render does not render web mobile responsive css (Bootstrap)

[donwilly2010]

Weex is a very wonderful tool. I have successful run the tool on our development environment and it was fine.
But then I noticed a bug. I believe the main purpose of Weex is to share same code based from Vuejs for Web and Mobile development.
However, Weex Vue Render used in latest version of Weex does not render existing mobile responsive web css such as Bootstrap. This means that existing Vuejs codes on vue cli cannot be migrated to Weex. This is a bug and a major set back as its not realistic for every Weex developer to develop Vue application from ground up on Weex as there are a lot of existing Vue applications that needs to be migrated to Weex.

Please how can this issue be resolved by Weex Vue Render
